Modular UPS
A hot-swappable modular UPS from 10 kVA to 1.6 MW with no-master-slave parallel and N+1 redundancy, up to 97% efficiency, engineered for data centers and mission-critical loads that grow over time.
Key applications: data centers and colocation, government and mega projects, banking and enterprise, large telecom sites.
Why Modular UPS
Hot-swap modular
Hot-swappable power modules let you scale capacity and service the system without shutting down critical loads.
10 kVA to 1.6 MW
One frame family scales from 10 kVA edge cabinets to 1.6 MW (1600 kVA) data-hall systems by adding 30 / 50 / 100 kW power modules.
N+1 redundancy
No-master-slave parallel with N+1 module redundancy keeps the load protected through any single module fault.
Up to 97% efficiency
Up to 97% online efficiency and ECO mode up to 99% cut energy losses and cooling demand at scale.
